arm: k3: Kconfig: Enable fTPM and RPMB support
Enable firmware TPM (fTPM) support via OP-TEE for K3 platforms with
MMC hardware. This provides TPM 2.0 functionality through
Microsoft's fTPM Trusted Application running in OP-TEE secure world,
using eMMC RPMB as persistent storage.
fTPM support in U-Boot provides the foundation for measured boot
and disk encryption use cases.
The ARM64 condition ensures these apply only to A53/A72 cores and the
MMC condition ensures fTPM is enabled only on platforms with eMMC
hardware support.
